Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a ruler to be used when a paper, a cardboard, a thin plate, a plastic sheet material or the like is cut into a rectangular shape having a required size or an arbitrary shape including a square by using a cutter knife.

[0002]

[Prior art]

 Conventionally, it was necessary to use a triangle ruler and a straight ruler with dimensions to cut paper, cardboard, thin board, sheet material, etc. into a square with the required dimensions. The following was used to cut a sheet material into squares with the required dimensions using the triangle ruler and straight ruler. First, place the triangle ruler on the sheet material you want to cut, and fix it by hand so that it will not move. Use a writing instrument such as a pencil to draw a right angle on the sheet material, obtain the required dimensions with a straight edge ruler, and mark with the writing instrument. Draw a rectangle of the required size on the sheet material again using the triangle ruler, straight ruler and writing instrument. Apply a straight edge to the drawn rectangle, fix it with your hand so that it does not move, and cut with a cutter knife. The above procedure was required.

[0003]

[Problems to be solved by the device]

 When using the cutting method that used a conventional triangle ruler, straight ruler, and writing instrument, it is difficult and accurate to draw a rectangle with the required dimensions accurately on the sheet material using the triangle ruler and straight ruler. I had no choice but to do it carefully and slowly. For this reason, it was troublesome and laborious. Then, it was necessary to apply a ruler to the drawn rectangle and fix it by hand so that it would not move, and then cut with a cutter knife. The drawn rectangle has a line width depending on the writing instrument, and depending on how the ruler is applied, it was difficult to accurately determine the squareness. The problem to be solved by this invention is to provide a right-angled ruler that anyone can easily and quickly cut a square of exact size without using a triangle ruler, a straight ruler and a writing instrument.

[0004]

[Means for Solving the Problems]

 The right-angle cut ruler according to the present invention solves the above problems and is as follows. The right-angle ruler according to the present invention comprises a combination of a metal straight ruler (1) and a straight ruler (2). One end of straight edge ruler (1) is vertically attached to the center of straight edge ruler (2) at right angles, and the point where the orthogonal point of the heavy edge of straight edge ruler (1) and straight edge ruler (2) is number 0 is displayed. Are provided in three directions. This proposal has the above configuration.

[0005]

[Work]

 The straight edge (2) is brought into contact with one end of the sheet material to be cut and fixed by hand, and the orthogonal end of the sheet material is cut along the straight edge (1) with a cutter knife. At this time, by adjusting the scale of the straight edge ruler (2) at the position of the required dimension from one end of the sheet material, the required dimension and the perpendicularity can be obtained at once. Similarly, a straight square (2) is brought into contact with the side that has just been cut, and cutting with a cutter knife at the required size is repeated three times, so that an accurate square can be cut easily and quickly. Wear.

[0006]

【Example】

 Hereinafter, description will be made based on examples. The upper end of the straightedge (1), which is a vertical scale, is vertically attached to the center of the straightedge (2), which is a horizontal scale, and the two orthogonal points where the horizontal and vertical scales are attached are set to 0. Positional size indication is provided in three directions. At the 0th position on the horizontal scale, make a notch with a width that allows the blade of the cutter knife to enter, and either apply anti-slip processing or paste a non-slip member on the back surface of the vertical scale. The above is the embodiment of the present invention.

[0007]

[Effect of device]

 By cutting a sheet material using the right-angled ruler of the present invention, it is easy to obtain a rectangle with a precise square angle and high accuracy without using a triangle ruler, a straight edge ruler, a writing instrument, etc. Can be cut into In the conventional method, a triangle ruler was placed on the sheet material to be cut and fixed by pushing it from above with a hand, but in the right-angle ruler of the present invention, the edge of the sheet material is brought into contact with the edge of the horizontal scale. Since it can be fixed, it is much easier to fix. The following two points are not shown in the figure, but the back of the vertical scale has a non-slip surface, so the fixed state is more stable. The notch is provided at the 0th position of the horizontal scale in order to cut from the outside of the end of the sheet material to be cut without damaging the blade of the cutter knife. In addition, unlike the conventional method, the ruler of the present invention is applied directly to the sheet material to be cut, and the necessary size is not applied to the sheet material drawn with a writing instrument on the sheet material. Since the scale part can be cut directly with the blade of a cutter knife, the accuracy is much more accurate than the conventional method, and no one is required to use it such as triangle ruler, straight ruler and writing instrument. However, it is possible to quickly perform cutting work with almost the same accuracy.
